To all whom it may concern: 7

Be it known that I, Gnome F. Pioxnrr, a citizen of the United States,and a resident of the city of New York, borou h of Brooklyn, in thecounty and State 0% New York, have invented a new and Improved Shaft forPaper-Rolls, of which the following is a full, clear, and exactdescription;

v This invention relates to supports for paper rolls and has particularreference to means for making a quick, easy, and effective grippingconnection between the .roll of paper, or its equivalent, and thesupporting shaft.

Among the objects, therefore, of this invention Is to provide a air ofcones for cooperation with the sha t, said cones being movable freelyinwardly fromthe ends of the shaft into enga ement with the roll ofpaper, and each of t e cones being provided with a dog or pawlcooperating with a t to prevent accidental outward movement thereof.

a Another objwt of the invention is to provide for at least one of saidcones, an improved means for projecting it forcibly into the adjacentend of the roll to ,set up the desired amount of'frictional grip.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein,

still for the purpose of illustrating a practical embodiment thereofreference is had to the accompanying drawings, in which like referencecharacters designate the same parts in the several views, and in whichFigure 1 is a vertical longitudinal section indicating my improvementapplied to a roll of paper, the intermediate portions thereof beingbroken away; and

Fi 2 is a verticaltransverse the me 2-2 of Fig. 1.

The roll of paper is indicated at 10 and as usual. has an open center10' through which the shaft 11 is ada jected. The shaft is provi ed onone side with a lo itudinal groove or keyway 12,

section on and along t e opposite side or any other convenient portion,the shaft is provided wlth. a series of teeth 13 at each end the teethbeing'inclined toward the midle of theshaft from both ends.

At one-end of the shaft is shown a head vided at its out er end ted tobe pro 1 1 having a-cane 15 extending toward the other end oftie shaftand adapted to proect into the opening of the roll. This head is adaptedto be shoved into or toward the .roll as faras convenient by directoperation and 'will there be locked from outward movement by means of adog 16 having teeth en aging one or more of the teeth 13 of the a t, thedog being projected into such engageme. it automatically b means of aspring 17 carried by the bee and prowith a finger-piece 18 for releasingit when desired.

For the other end of the shaft, is provided another lead 19 havin a cone20 1'0- jectabie into the other end 0 the roll. he outer end of tie head19 consists of an extension 21 in tle nature of a sleeve fitted to theshaft and provided with an external screw thread 22, preferably of left'hand character. Bei ween the threaded portion and the cone 2b is areduced zone 23. The cone members 15 and 20 are held from rotationaround the shaft by means of keys 24 and 25 of any :uitable characterprojecting into the keyway 12.

26 indicates LII abutment member fitted slidably upon the shaft adjacentthe outer end of the extersion 21 of the head last described. Theabutment carries a dog 16, spring operated in a manner described inconnection with the head 14, adapting the abutmentmemb er to be forceddirectly toward the roll, but preventing movement thereof in the otherdirection. The abutment carries a flan e or collar 27 at its inner end,and just within this collar the face of the abutment is provided with aball race 28.

' 29 indicates a iand wheel secured to a hub 30, the main portion ofwhich is threaded tocooperate dire ctly with the threaded portion 22 ofthe e: :tension. The outer end of the hub is provided with acircumferential groove 31 into which screws 32, or their equivalent,project from the collar 27 of the abutment, and at the end of the hubis. ro-' or screws 32. The length of the hub is eubstantially equal tothat of the threaded extension 21 and the smooth zone 28, and when the.parts are assembled, .the hub is turned around the head so as to bringthe inner end thereofclose to the cone or with the outer ends of thehead and extension lying substantially in the same plane. One or moreset screws 35 are projected through the mner end of the hub into easy006 ration with the smooth zone portion 23 of e head. These set screwslimit the outward movement of the hub with respect to the headextension. v

A series of dowel pins 86 are secured in the head extension 21 parallelto the axis of the shaftvand projecting into corresponding sockets 37forms in-the 'abutment member 26 and serve to prevent relative rotationof the abutment member. -'These dowel. pins do not revent, however, themovement of the he 19 forwardly away from the abutment member.

This portion of the invention just described will be' forced directlyinto contact with the end of the roll-of paper similarly to the settingof the head 14, and then to tighten the heads inthe ends of the roll,the

operator will turn the hand wheel and hub toward the right, causingthereby the cones to approach each other forcibly, the head.19 beingmoved directly by the threads of the extension, the abutment memberbeing stationary with respect to the shaft, and the other cone beindrawn into the roll by virtue of the reaction of the shaft and theabutment member. The cones obviously may be of any desired length orinclination, and the threaded portion 22 of the head extension will belong enough to effect the desired tightening lg a single directoperation. To remove the is very sim 1e and. consists essentially ofturning the and wheel, first, to the left to relieve the pressure uponthe ends of the roll and then by releasing one or the other of the dogs,16, the adjacent head may sllhipfied directly from the-shaft and thenthe with the other head-attached may. be

the shaft if desired.

aft from the roll, the operation slipped freely in the oppositedirection from the roll, or both heads mayflae removed from I claim:

\' I 1. The combination with a shaft for paper rolls or the like, a leadsecured to one end head having a conical inner 65 of the shaft,

end slidably fi d upon the other end of the shaft and adapted to bemoved by hand directly into contact with the roll, the latter head beingprovided with an extension hav ing a threaded exterior surface, a handwheel having an internally threaded hub cooperating with said threadedsurface, an'

abutment member slidable longitudinally of;

the shaft freely in one direction, means to control the sliding movementof the abutment member in the other direction fromthe Y shaft, meansconnecting the abutment member and wheel hub to prevent endwiseseparation, but permitting relative rotation of the hand wheel, andmeans to prevent rotation of the slidable head.

2. In a device of the character set forth, the combination with a shafthaving a head secured at one end thereof, of a head slidable along theother end of the shaft, said head 76 having at its outer end anextension havin a threaded ortion and -a smooth reduce ortion, a hufitted upon said extension and aving an internally threaded portioncooperating with the threaded portion of the ex- 80 tension and havingmeans projecting. inwardly from the other portion of the hub intocontact with the reduced smooth portion of the extension, the hubserving to force the head in'one direction until limited by saidinwa'rdl projecting means, an abutment slidably tted u on the shaft,means to connect the hub wit the abutment member for free rotation butpreventing endwise displacement of the hub, and means extend- 00 ingbetween the head extension and the abutment member preventing relativerotation of these parts but permitting endwise movement of one withrespect to the other.
